Patent CA-2506321-A1 (CA)
Title: Well treating process and system
Inventor: JONES LLOYD G
IPC: E21B33/12
Filed: 2003-11-13
Abstract: A method for the treatment of a subterranean formation penetrated by a well in which, first and second flow paths are established from the wellhead into th e vicinity of the formation. A plugging fluid comprising a suspension of a particulate plugging agent in a carrier liquid is circulated into the first flow path and into contact with the wall of the well within the subterranean formation. The carrier liquid is separated from the particulate plugging age nt by circulating the carrier liquid through a set of openings leading to the second flow path, which are dimensioned to allow the passage of the carrier liquid while retaining the particulate plugging agent in contact with the se t of openings. The circulation of the plugging fluid continues until the particulate plugging agent accumulates to form a bridge packing within the well. Subsequent to establishing the bridge packing, a treating fluid is introduced into the well through the first flow path and in contact with the surface of the formation in the well adjacent to the bridge packing. The treating fluid may be a fracturing fluid under or an acidizing fluid. A clea n- up fluid is circulated into the second flow path to remove the bridge packin g.

Abstract: A melt distribution block for a co-extrusion die has a generally annular body, for example in the shape of a conical frustum. The annular body has opposed front and rear faces and opposed inner and outer faces. Inlets at the outer face have channel ports for accepting flow of melted polymer into the distribution block. Flow controlling valves independently control the flow of the melted polymer through each of the channel ports. Melt flow channels on the front and rear faces between the inner and outer faces are in fluid communication with the channel ports. A thermal insulation layer within the distribution block between the front and rear faces separate all or part of the melt flow channels on the front face from all or part of the melt flow channels on the rear face. Such blocks together with separator blocks may be axially stacked front to rear around a central mandrel to form an extrusion die suitable for making blown films into tubular form.

Title: Maintaining graphical presentations based on user customizations
Inventor: WRIGHT DAWN
IPC: G06F3/0484
Filed: 2005-08-29
Abstract: A method and system for rendering graphics based on user customizations in a computer graphics application are disclosed. The customizations relate to various properties of one or more graphical elements in the graphic. Such properties include positioning, size, formatting and other visual attributes associated with the graphical elements. These properties may be defined as either semantic properties or presentation properties. Semantic properties are persistent across all graphic definitions.  Presentation properties are specific to the graphic definition to which each particular graphic belongs. Thus, a customization to a semantic property of a displayed graphic is preserved in memory for application not only to the currently displayed graphic, but also to all other graphic definitions that may be displayed in the future. In contrast, a customization to a presentation property is only preserved for the currently displayed graphic, and thus not preserved for all other graphic definitions.

Abstract: The "Traffic Interval Signal Device" indicates to the vehicle driver the length of time for a green traffic signal light. The invention can be implemented at existing traffic lights; it is optimally used at highways and main thoroughfares. The signaling device uses display panel to present visually time remaining for a "green" light signal at traffic controlled intersection.  This will aid in the prevention of crossing the intersection in hazardous conditions (Red light signal). The case for the "Traffic Light Interval Signal Device" can use many types of lighting components: light emitting diodes, Liquid crystal display, and standard bulbs. The interval traffic light uses four segments (or the amount required) to represent elapsed time. The left segment can indicate a left turning signal by flashing for a defined time period. When the traffic controller sends the signal for a green light all segments of the traffic light shine green.
